Careiage-perche



UNITED STATES PATENT OFFICE.

LEWIS E. STILWILL, OF FRANKLINVILLE, NEW YORK.

CARRIAGE-PERCHE.

Specification of Letters Patent No. 8,568, dated December 2, 1851.

To all whom 25 may concern:

Be it known that I, LEwIs E. STILwILL, of Franklinville, in the county of Cattaraugus and State of New York, have invented a new and useful Impro-vement in Vheel-Carriages, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, which forms part of this specification and in which- Figure l is a plan of a portion of a ear riage with my improvements applied thereto and F ig. 2 is a vertical longitudinal section of the same.

The object of my invention is to relieve the turning plates or fifth wheel of a carriage, the king bolt, and the perch fro-m strain when the forward wheels are running over an irregular surface and it consists in passing the forward end of the perch through a tubular sleeve formed upon the turning =plate or fifth wheel, by which means the forward wheels and their axletree are permitted to rock with the requisite freedom without straining the perch, the king bolt or the springs.

In the accompanying drawing A is the hinder axletree, which is secured to the hinder extremity of the perch Bin the usual manner. The forward extremity of the perch is fitted with a spindle c which enters into a pipe Z formed upon the turning plate E; the front extremity of this spindle projects through the pipe of the turning plate and has the front spring bar F secured to it in such manner that the front of the wagon body, which is mounted upon the bar F, always maintains a position parallel to the hinder axle however much the front axletree may be rocked or turned. The lower turning plate Gr is secured to the front axletree I-I in the usual manner and the turning plates are connected by the king bolt e' and by a flange o.

It will now be seen that the front axletree can not only turn in a horizontal plane upon the king bolt as an axis to permit the wagon to turn horizontal curves, but that the front axle tree can also rock or turn in a vertical plane upon the erch spindle c as an axis to permit either ore wheel to rise and surmount an obstacle without aecting any other portion of the vehicle, and without twisting the perch or straining the king bolt or the body of the carriage. This arrangement also permits the turning plates to be put together rigidly without the necessity of allowing any play to compensate the twisting and strain which are necessarily incident to traveling on rough roads.

It is evident that the construction of my improved running gear may be modied without overstepping the limits of the invention and I contemplate so modifying it to adapt it to the varying circumstances which may occur.

Vhat I claim as my invention and desire to secure by Letters Patent, is-

Constructing the front extremity of the perch so as to form a spindle, which passes through a tube on the turning plate to connect itv with the front axletree, and at the same time to form a hinge on which the frontaxletree can rock, the latter being a new duty additional to that which the forward extremity of the perch has heretofore performed; thus increasing the efficiency without increasing the complexity or cost of the coupling.

In testimony whereof I have 'hereunto subscribed my name.

LEWIS E. STILVVILL.
